Rules – data encoding Identifier Data encoding rule ER-01 The special activity area shall be encoded as: a new Event, for which PERMDELTA and subsequent BASELINE Time. Slices shall be created; and a new Airspace, for which PERMDELTA and subsequent BASELINE Time. Slices shall be created; the property "event: the. Event" of the Airspace Time. Slices shall refer to the Event mentioned above. ER-02 The Airspace BASELINE shall contain one Airspace. Activation object with status=ACTIVE, IN_USE or INTERMITTENT (as appropriate) which shall also include the "activity" data and the values "FLOOR, uom=OTHER" for lower. Limit and "CEILING, uom=OTHER" for the upper. Limit of the associated Airspace. Layer. ER-03 If the area activity is limited to a discrete schedule within the overall time period between the "start time" and the "end time", then this shall be encoded using as many as necessary time. Interval/Timesheet properties for the Airspace. Activation with status ACTIVE/IN_USE/INTERMITTENT of the BASELINE Timeslice. See also the rules for Event Schedules. ER-04 If a schedule is provided, then the Airspace BASELINE shall contain a second Airspace. Activation object with status=INACTIVE, which shall explicitly specify the times not covered by the activity schedule. This shall be done automatically by the system and should not be visible to the operator. The "INACTIVE" times shall not be translated into NOTAM text. See also the rules for Event Schedules. ER-05 If one or more "exclude airspace" are specified, each shall be encoded as an Airspace. Geometry. Component with operation=SUBTR, operation. Sequence as dictated by the order of the element, contributor. Airspace/Airspace. Volume. Dependency. dependency=FULL_GEOMETRY and pointing to the airspace concerned. In addition, when the AIXM 5. 1 encoded data is provided to a client, the data corresponding to the Airspace. Volume(s) of the controbutor. Airspace (lower. Limit, lower. Limit. Reference, upper. Limit. Reference, horizontal. Projection, etc. ) shall be copied in the Airspace. Volume(s) of the current Airspace. This will provide a complete description of the current Airspace, eliminating the need to traverse the xlink: href in order to get the full geometrical information. The activity types that do not match a pre-defined value in the Code. Airspace. Activity. Type shall be encoded as follows: captive balloon -> activity=OTHER: CAPTIVE_BALLOON kite activities -> activity=OTHER: KITE demolition using explosive devices -> activity=OTHER: DEMOLITION mass movement of aircraft ->activity=OTHER: ACFT_MASS_MOVEMENT flying in formation -> activity=OTHER: ACFT_FORMATION aerial survey/photogrammetric flights -> activity=OTHER: AERIAL_SURVEY

Rules – data encoding ER-08 It is recommended that an alphanumeric designator is allocated to a temporary area, in order to facilitate it's identification on graphical representations (such as airspace activity maps) and verbal communication. The composition rule is derived from the ICAO Annex 15 rules for P, D, R area designators: CCLnnnn-yy, where: • CC is the Country Code; this could be expanded into a full FIR identifier if necessary to have a finer granularity of the airspace reference; • L is a letter that corresponds to the area type; • nnnn is a number, unduplicated during the same year, within the State or territory concerned; this could also be the NOTAM number; • yy are the last two digits of the year date when the area becomes effective
